Celebrities who have spoken out about mental health

Keira Knightley

In an interview with The Hollywood Reporter, the actress opened up about her struggles with post-traumatic stress disorder. She revealed the breakdown was caused by criticism of her acting skills, after a string of successful films like "Bend It Like Beckham" (2002) and "Love Actually" (2003). “I did have a mental breakdown at 22, so I did take a year off there and was diagnosed with post-traumatic stress disorder because of all of that stuff.”
